#1 Aero Precision 5.56 AR 15 BCG
The first on the list is a good choice for good money. This BCG is rather durable thanks to the nickel-boron finish and an 8620 tool steel carrier with a 5.56 9310 steel bolt. In addition to this, the bolt carrier group is shot-peened and magnetic particle inspected. It’s easy to clean, and it looks great. The forward assist serrations ensure smooth work, so you can count on this model.
#2 Lantac Enhanced Full Auto Style AR 15 BCG
The next model costs more and offers more as well. It’s a high-quality bolt carrier group machined from 8620 steel with an innovative nickel-boron coating with advanced UTC EXO, which means this BCG is durable and it ensures smooth operation. Thanks to the unique design and forward porting, the upper receiver’s pressure is reduced. It’s a well-designed, reliable model that is compatible with full- and semi-auto rifles. Plus, it comes with a lifetime warranty.
#3 Faxon Firearms Gen 2 9mm PCC AR15 BCG
If you think that there is nothing that can surprise you, just look at this model. Although it is cheap, it offers an interesting solution for your AR-15. This is a 9mm bolt carrier group that is dual compatible with Colt and Glock. Made of solid 8620 steel with a salt bath nitride finish, this BCG can be a good add-on for your fire-arm. Due to the ramped bottom, you can use any common trigger. Moreover, it’s compatible with MP5 magazines, M-16 (full-auto) rifles, and JP Enterprises buffer systems.
#4 ODIN Works Nitride AR 15 BCG
This group is for 6.5mm Grendel caliber, and it’s also made of case hardened 8620 steel. The nitride finish allows you to use less lubricant, saving a low friction rate. The bolt carrier group is Mil-Spec compatible, high pressure tested, and magnetic particle inspected. The gas key is properly staked. This is a good purchase if you are looking for this caliber.
#5 Armament AR-15 Bolt Carrier Group
Another good solution for 5.56x45mm NATO, .223 Remington calibers for M-16 and AR-15 rifles. An MPI tested 9310 steel bolt and 8620 tool steel heat treated and case hardened carrier with a tool steel properly staked gas key ensure enjoyable, smooth shooting for a low price. You can be sure about durability if you decided to install this bolt carrier group.
#6 JP Enterprises Complete JPBC AR 15 BCG
If you are looking for something unusual that will give more space for customization and improvements, this bolt carrier group for .223 Remington will suit you well. First of all, it’s a durable thing, that will last endlessly. Besides, it offers a range of features you can’t find anywhere else: increased firing impulse, improved reliability and accuracy, reduced pin wear, innovative ergonomic design. All these features are possible, thanks to the great JPBC compatibility.
#7 Griffin Armament Enhanced Mil-Spec AR 15 BCG
We love this model because it’s very balanced. For a cheap price, you can get a well-designed 5.56x45mm NATO, .300 AAC Blackout bolt carrier group for AR-based rifles that consists of an 8620 alloy steel carrier, a 9310 steel bolt, and a 4340 alloy steel cam pin with extractor. The melonite QPQ finish makes operation smoother and reduces the use of lubricants. The bolt is heat-treated and shot-peened, and the gas key is staked properly. You will be also glad to know that the crane O-ring is used here to increase extraction reliability.
#8 F-1 Firearms Durabolt 5.56 AR 15 Bolt Carrier Group
Regarding this model, there is nothing much to describe because it’s just a good, durable bolt carrier group that is designed for AR-15 platforms and compatible with any Mil-Spec components. This BCG is rated for full-auto rifles, which is also a good advantage. High-quality coatings that are used here ensure not only durability but also a smooth shooting experience.
#9 Aero Precision AR15 6.5 Grendel AR 15 Bolt Carrier Group
Another inexpensive bolt carrier group for 6.5mm Grendel. The material used here is standard 8620 steel with a black nitride finish that reduces friction. The bolt is shot-peened, HPT tested, and MPI marked. Thanks to the forward assist serrations, the BCG works better. Besides, the installed O-ring makes the extraction easier.
#10 ODIN Works AR 15 Bolt Carrier Group
ODIN likes to make customers happy with affordable solutions. This bolt carrier group has Mil-Spec dimensions and it’s used for AR-15 and M4 rifles for .223/5.56mm, .300 Blackout calibers. The material used to manufacture this BSG is case hardened 8620 steel finished with black nitride, which increases durability and lowers friction rate. There is also an O-ring on the extractor. High pressure tested and magnetic particle inspected.
#11 Midwest Industries 5.56/AR15 C158 AR 15 BCG
This model is a bit less durable, compared to the previous ones. The bolt is made of Carpenter 158 and it’s also heat treated, shot peened, precision ground, and magnetic particle inspected. The black nitride finish, however, does its work and increases durability, making operation smoother. Other elements are also reliable. The 4140-billet gas key, for example, is torqued with grade 8 fasteners and has the proper positioning. The O-ring is also used.
#12 Guntec USA AR-15 Bolt Carrier Group Mil-Spec BCG
A very standard bolt carrier group with an 8620-steel bolt carrier and an MPI 9310 bolt coated with PVD that offers an enjoyable shooting experience by lowering friction rate and ensuring good durability. The only curious thing about this model is its color because it’s a kind of rainbow gradient that looks unusual. However, you will never get disappointed by this BCG.
#13 TRYBE Defense Milspec AR15 Bolt Carrier Group
One more cheap bolt carrier group that works with 223, 5.56, and .300 AAC(BLK) calibers. This model is machined from 8620 steel and has a nickel-boron finish that makes the BCG even more reliable. The bolt is high pressure tested and magnetic particle inspected. Other components, such as carrier, gas key, cam pin, and firing pin also have the highest quality.
#14 Phase 5 Tactical AR-15 Bolt Carrier Group
The last model on the list is the cheapest one. It doesn’t mean that it’s the worst one, but your budget is limited, you should take a look at this bolt carrier group. The bolt has a phosphate finish and it is high pressure tested and MPI marked. Note that the gas key is not staked here. It’s not the best choice among all these models, but if you need a .223 Remington/5.56 NATO BCG for a low price, you can definitely take it.
BONUS: CMMG, Inc 22LR Mk4 AR 15 BCG (+Barrel)
You can also consider buying a barrel kit with a bolt group. This one is suitable for M4 profiles and it’s made of 4140 Chrome Moly steel with salt bath nitride finish in and out. The overall length is 16.1 inches. This model works with .22 long rifle caliber, which is not usual nowadays. Still, it doesn’t have a high price!
